lMPR-O YEMEN T in WATER-'PURIFYING APPARATUS.

Specification forming part of Letters Patent No. 181,468, dated August 22, 1876 application filed i i July 10, 1876. i

have invented certain new and useful Improvements in Apparatus for Purifying Water; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying draw-.

ing, which forms part of this specification. v

This invention relates to apparatus of the same general character as that described in Letters Patent No.146,940, granted me J anuary 27, 1874, in which the water to be purified is subjected to separate and consecutive cleansing operations, beginning by commingling steam with the water, and afterward subjecting it to the action of suitable chemicals, whereby foreign matters contained in the water'are precipitated and collected in the bottom of the apparatus, or separately collected in the purifying-chambers of the apparatus, while the water flows out deprived of its impurities. Such apparatus, on which this invention is an improvement, provides for supplying water to steam-boilers deprived, in a cheap and effective manner, of various injurious substances, mechanically and chemically v combined with the water, exhaust or waste steam answering to mingle with the water under treatment, and the apparatus being a continuous-workin g one.

The invention differs from my former appa ratus in certain peculiarities of construction and combinations of parts, including a separate and externally-arranged tank or vessel for heating and depriving the water of certain of its impnrities, and for the condensation of -the waste steam, which is admitted down into and through the water, that, after being thus heated and purified, passes off by an overflowpipe to a second and lower tank.

The invention also consists in a certain constructionof this second tank, which receives the heated water, with a separate compartment formed in it for the bucket-wheel, which worksthe chemical device that distributes the chemical agent or agents employed to'further purify the water in a tank beneath the hotwater tank.

condensing tank or vessel. This tank, which may be of any suitable material and shape, is

heated water, but may otherwise occupy any desired relation with the latter. Said tank A is fitted with a cover; a pipe, b, which may be controlled by a valve, for supplying the tank 3 with the water to be purified; a pipe, 0, leading down into the tank, below the surface of the water in the latter, for introducing steam within the body of water in the tank; and an" j overflow-pipe, d, which may be, in part or in whole, of rubber or other flexible material, to prevent transmission to the other tank or A, said overflow-pipe d connecting the detached tank A with the tank B.

The steam may be supplied .to the pipe 0 from any convenient source. Said tank A, havto be purified, as described, not only constitutes an effective heater, but provides for a complete separation or precipitation of the sulphate of lime contained in the water, and for purifying the Waste steam from greasy matters mixed with it; also provides for the most thorough condensation of the steam.

These advantages are mainly due toqthe mode of introducing the steam by bringing the water and the steam in direct and intimate contact, and such mode of'opera'tionis only practicable when the tank A is a separate one, inasmuch as the vibrations consequent upon the introduction of the steam into the the fine particles of chloride of barium or other chemical agent employed in the remaining portion of the apparatus.

Ais the separated water-heating and steanr arranged outside of,'and placed at'a higher elevation than, the tank B, which receives the tanks of the vibrations consequent'upon introducing the steam among the water in the tank ing the steam admitted to it within the water Water would render impossible the deposit ofontinually exposed to the influenceof steam;

vithout any disturbing vibration. Conseuently, I am enabled to obtain a complete u'ecipitation of the carbonate of lime sepaated by the action of the steam.

The bucket-wheel G, which works the chem-1 cal-solution distributer H, that draws up the :hemical ingredients. or solutions (sueh ascar-k )onate of soda and chloride of bariumlfrom' .he pan I of-a'box or vessel,J, supplyingsaid urifying agents, operates directly and with-:- nit theinterveution of gearing to actuate the;

:hemicalsolution distributer H, by the ar-;

rangement of the latter, which consists of one )r more revolving dip-tubes on the axle of the 1 Jacket-wheel. This chemical-solution lifter or iistributer B conducts the chemicalsolution iirectly into thehollow nave g'onthe axle of the bucket-wheel, from whence said solution drops into a funnel, h, which conveysit to the; first compartment in the tank 0. The direct connection of the bucket-wheel G with the BhGlIliCflLSQllltiOll lifter or. distributeralso re-: duces the liability of leakage by dispensing with astufting-box, and is generally much simpler than the arrangement described in my patent of January 27,1874,hereinbefore referred to.

There may be a series of chemical-solution distributers E, if desired, all in communication with each other byhollow naves,so-that one funnel, h, will serve to receive an the chemical agents or solutions employed.

The tank 0 has holes in its bottom, from which pipes 70 k, furnished with stop cocksor plugs, lead. These pipes serve to clean or empty the lower tank 0 of 'deposited'matter such as gypsum, sulphate of lime, chloride of v barium. By means of these pipes the tank 0, which, as in my former apparatus, is constructed with reversely-arrange'cl upper "and lower vertical partitions t, to promote circulation, makes it practicable to clean the tank 0 without stopping the working of the appara:

tus.

1n the operation of the apparatus, the wa-: ter to be purified 'is introduced ;hyfthe pipe -bj to the tank A, near its bottom and steam by; thepipe 0 brought in director intimate con-1 tact with said water The water is thus'heated to a'very high degree, and consequentl'y deposits the carbonate of lime contained in it. The jcondensed steam wi lkseparate all greasyistrbstances, and the diflerent'igreasy 0, be saponified by the chemical agents introduced within the said tank, and fall to the bottom *offlthe "latter mixed with the heavy sulphate of barium.

The heated water and any non-condensed steam pass through the overflow-pipe 01 into the largest compartment of the tank B, from whence the water passes by an overflow channel or outlet, s, into the compartment E, and -'falli ug on the buckets of the wheel G rotates the latter. From thebottom of this compartment E the water, after having worked the wheel, flows, by apipe, 1, into the lower tank 0, near its one end, and passes from thence through said itank Cftothe oth r endjof the latterffro'm whence it Lpasses'oif purified by "an outlet, m, it-having been ex osed, during *agent or'agents employed to jpu'rify it. t Steam forming or accumulatin g in the tank- Bl passes bya lpipe, 'n, which reaches above the level of 'the' water in said tank, tothe re'ar or end compartment of the tank 0, and es: capes from "thence byai pipe, i',into the outer alr.
